Application filed pbrnary 1, 1322:. serial No. 533,161.

To all whom it may cmwewt:

Be it known that CHARLES D. Angus, citizen of the United States, residing at St. Augustine, in the county of St. John and State of Florida, has invented certain ew and useful Improvements in Divided: ull Vessels, of which the following is a spec1fica tion, reference being had therein to the accompanying drawingsf The invention relates to divided hull vessels and has for its object to provides vessel comprising spaced hulls in parallel relation to each other, the ends of said hullsloeing connected toq'ether by yolres hic yoke-s arch the ends of the vessels and are raced by angularly disposed brace bars. Also. to provide between the hulls an endless belt extending around rollers and sprockets, sa d belt comprising afcentrally disposed drive chain, side cables, said, side cables and cantrally disposed difive chains havrngsqcur'ed thereto spaced transversely disposed paddies, which travel longitudinally engag ng the water, thereby forcing the vessel for vvardly or rea rvvardly, i

A further object is to form the paddles from sheet iron, each padd 1e be'in T-shaped in'transverse cross section and iornied by low ing h et ma e a i sel a nd fleasing the ends ofthefsheet to the plane. Also to provide apertures in the, anges and registering apertures in the bedy the paddle ad acent its ends, and'throiigh which apertures the cables pass, thereby? holding the paddles on the cables against slipping. and at the same time allowing the cablestp easily pass over the flanged guide, rollers.

" A further object is, to provide means whereby When the vessel is tied. to a dock or the like, the current or the'stream may be,

utilized for moving the paddles nd else-j tricity generated for lihtlng or oter purposes aboard the vessefi A further object is to provide the vessel with an engine whereby the vessel may be propelled through the medium of the pad- YVith the above and other-objects in View: the invention residesin the combination a d arrangement of parts as hereinafter; forth, shovvn in the drawings, described and claimed, it being "underdog H changes in, the precise emiodiment 'of the invefitioninay be made vvit in the scope of what is claimed Without departing from the spirit of the invention.

The yokes 3 are provided With og vals aped members 4, which receive the ids 5 of the hulls 1 and 2 and are secured to sald ends by means of rivets 6. Extend r'ng inwardly and diverging from each other rem the transverse portions 7 of the yokes are bracesB, which braces brace the hulls espgchallyi on strains on any of the quarters 0 inner sides of the ogival-shaped members 4 at9. Itvvill be seen that the yokes 3 con- 11601: the hulls 1 and 2 together rigidly and brace the bulls in relation to each other. mountedin bearings 10 in the {megs es of the, hulls 1 and 2 are shafts 1, winch shafts are provided, with flanged pulleys 12, which are rotatably mounted thereon, and around which pulleys cables l3 jegtend." The cables 13 pass over pulleys 14 rotatably mounted on the transversely disposed drive, shaft 15. It will be seen if; at as the drive, shaft 15 is rotated, that t e cables 13 which are endless, move according to, the direction of movement of the aft 15 However the positive movement 0- cables 13 is insured by the connection thereof to, the drive chain 16 through the medium of the transversely disposed paddies ii. The drive chain 16 extends over a drive pulley 18 carried by the drive shaft 15 and over idle sprockets 19 rotatably mounted on the shafts 11. Thus it will be seen that W1 en the drive shaft 15 is rotated that the paddles 17 which are disposed be low the waterline 20 of the vessel will e'ng a'g e the water and force the vessel fory o yrearyvar'dl accordingv to the di- 1; ion oi? rqtat on cg he sh 'ft ji15. It w ll e'see'n that the driving mec' a'nis'm is disposed between the hulls thereby maintaining the vessel on an even keel, and at the same 1 The braces 8 merge into the,

time disposing the propelling means of the vessel where it will not interfere with the vessel goin along side of a deck.

The pad les 17 are formed from a single sheet of material bent to a T-shape as shown in Figures 4 and 5. The sheet is bent upon itself as at 21, thereby forming engaging members 22, the lower ends of which are again bent at 23, thereby forming outwardly extending flanges 24 which are in the same plane. The flanges 24L rest upon the cables 13, and the drive chain 16, and are secured to the drive chain 16 at 25 substantially centrally of the paddles. The cables 13 pass through apertures 26 in the flanges 24, and thence through registering apertures 27 in the members 22. It will be seen that right angle bends are in the cables 13,.which bends prevent slipping of the paddles 17 on the cables and at the same time obviate the use of clamping members for securing the paddles to the cables, which clamping members would interfere with the passage of the cables 13 over the idle pulleys 12and 14. It will be seen that when the corners 28 of the cables 13 reach the pulleys they will pass between the flanges 29 thereof, and at the same time the cables will not interfere with the passage of the paddles 17 around the pulleys 12, sprockets 19, pulleys Hand the sprocket 18. When the paddles 17 are in their lowered driving position the flanges 24 of the paddles will engage the cables 13 and drive sprocket 16, thereby maintaining the paddles 17 in vertical positions during the driving operation. I

The drive shaft 15 is driven from an engine 30 through the shaft 31, which shaft is connected to theshaft 32 by means of bevel gears 33. Feathered on the shaft 32 is a clutch member 34, which clutch member, when thrown into engagement with clutch member 35 by means of the lever 36, allows power to be transmitted from the engine 30 to the drive shaft 15, thereby driving the sprocket chain 16, and the propelling mechan1sm.

Disposed on the hull 1 is a motor gener-l ator 37, which generator is driven by the drive shaft 15 through a gear train 38. It will be seen that the motor generatormay generate current for various purposeson the vessel, such for instance as the lighting circuit, operation of capstans, hoisting appa ratus or for any other purpose. When the device is in a stream where there in a current and is tied to the dock or anchored in the stream, it is obvious that the motor generator 37 may be operated when'the clutch members 34: and 35, which connects the drive shaft 15 with the engine 30 are out of engagement, thereby allowing the lighting circuit of the ship to be maintainedand auxiliary machinery operated through the medium of electric current to be maintained in operation.

From the above it will be seen that a divid'ed hull vessel is provided, which is simple in construction, the hulls rigidly held and braced together and a propelling means provided for the vessel which is protected, and which may be utilized for operating auxiliary machinery or lighting circuits through a motor generator.

The invention having been set forth what is claimed as new and useful is 1. The'combination with an endless ropelling means forvessels, said propel ing means comprising an endless s rocket chain extending over spaced sprocliets, endless cables extending over flanged pulleys in axial alignment with the sprockets, of transversely disposed paddles connected to said sprocket chain and cables, said paddles being 'T-, shaped in cross section and having their opposite flanges in the same plane and in engagement with the chain and cables, said cables extending through apertures in the flanges of the paddles and through apertures in the'main body of the paddles adjacent the inner sides of the flanges.

2. The combination with an endless propelling means for vessels, said propelling means comprising a centrally disposed driven sprocket chain and cables, said sprocketchain passing over sprockets, said cables passing over flan ed pulleys, of transversely disposed paddles carried by said chain and cables, said paddles being T- shaped in cross sectionand having their opposite flanges in engagement with the sprocket chain and cables, said cables extending upwardly through apertures in the opposite flanges adjacent the inner sides thereof and transversely through apertures in the main body of the paddles adjacent the flanges.

3. The combination with endless cables of the propelling mechanism for vessels, of a transversel dis osed paddle carried by said cables, sai pa dle being T-shaped in cross section and formed from a single sheet of metal bent upon itself to form the main body of the paddle and having itsend terminating in oppositely extending flanges, said cables being connected to the paddle by extending upwardly through apertures in the oppositely extending flan es adjacent the main body of the paddle and through registering apertures in the body of the paddle adjacent the first mentioned apertures.
